*^-^* Hello! Im new and need help!

As a word of caution, Sailormoon cels are some of the priciest cels on the market.

While cels of Mamoru aren't difficult to find, some of the really nice ones can be rather pricey.

There are some of Mamoru-kun at the RS shop. Good luck finding what you're looking for!

I found 2 mamoru cels on ebay that may be to your liking:
